In E. coli, the DNA polymerase that handles most of the synthesis is DNA polymerase III. There are two molecules of DNA polymerase III at a replication fork, each of them hard at work on one of the two …

DNA polymerases are the enzymes that build DNA in cells. During DNA replication (copying), most DNA polymerases can “check their work” with each base that they add.

On the leading strand, DNA polymerase catalyzes the continuous synthesis of DNA in the 5' to 3' direction. However, on the lagging strand, DNA synthesis occurs in short fragments called Okazaki …

DNA polymerase III plays a crucial role in DNA replication, proofreading and correcting errors. It works alongside DNA helicase and other enzymes to ensure accurate replication.

DNA polymerase is the enzyme responsible for synthesizing new DNA. To do this, DNA polymerase moves along a template strand and adds complementary nucleotides one at a time to a growing DNA …

Humans and other eukaryotes have three different kinds of RNA polymerase: I, II, and III. Each one specializes in transcribing certain classes of genes. Plants have an additional two kinds of RNA …

Once the 3′ end of the lagging strand template is sufficiently elongated, DNA polymerase adds the complementary nucleotides to the ends of the chromosomes; thus, the ends of the chromosomes are …

The primary enzyme involved in this is DNA polymerase which joins nucleotides to synthesize the new complementary strand. DNA polymerase also proofreads each new DNA strand to make sure that …

In order to understand the biological function of DNA, you first need to understand its molecular structure. This requires learning the vocabulary for talking about the building blocks of DNA, and how …

The main enzyme involved in transcription is RNA polymerase, which uses a single-stranded DNA template to synthesize a complementary strand of RNA. Specifically, RNA polymerase builds an …
